This reminded me of Tim OReilly trying to explain how sed works back in the 1980's. In his case it was a monk/scribe instead of an imp. Nice work.

Is the sedation COW?

No, I was going for Page Fault[1], which, if I recall my comp. arch. lectures, suspends the requesting process until the required page has been read from disk and put in memory somewhere. So wall-clock time passes, but the process itself doesn't know about it until it resumes. Even then, I don't think it can know definitively why it was suspended - it could just as well have been pre-empted by some other task.
